The blogger. It is customary at The Economist to assign to a columnist as a pseudonym the name of a foundational figure in whatever the column purports to be about ("Lexington" for their USA coverage, "Schumpeter" for the coverage of business, &c.). One person will write the column for a period, and then move on.
